It's better than the title implies. They also broke the MRI machine because they hit emergency stop buttons instead of stopping for a couple seconds to ask how to safely handle removing the gun.
(I'm not sure the cost difference between a graceful shutdown and an e-stop and can't find information, but if it's 250k worth of fix, I'm betting it's significant.)
And they were there because the energy use of the MRI made them suspect it was a pot farm... in a legal state.
I agree with the legal state part, but it was not the energy use of the MRI; it was BS'd from the following:
Why would you conduct a raid without even finding out what the official listing for an address says they do there. Because in this case the bare minimum could have been 2 uniformed cops just ringing the bell.. or an undercover/plain clothes cop making an appointment. But no.. dicks out.. full raid.. probably good overtime.
Tinted windows, security cameras, and uniforms...rock solid proof of a weed farm. /s
That describes 90% of the businesses I shop at.
Why do you shop at so many weed farms???
Sounds like you buy a lot of weed.
I have no idea what that smells like, but this smells like a bunch of crap
That is… patently stupid.
Basically he smelled pot.
Thats the only suspicious thing in that chain of observations.
Literally every non-residential building has tinted windows in some way or another- it’s for energy conservation.
Every non residential and a fairly large number of residential buildings have cameras. Yes. To deter would be thieves, but mostly to show what happened and maybe whodunnit, if you’re lucky.
“Similar attire” what the fuck does that even mean? Uniformed? Scrubs? Shit. Everyone in almost every company all wear similar attire when going to work.
Usually job appropriate attire. Which means people doing the same job are going to be wearing “similar attire”.
“They appear to be wearing maintenance clothing- blue jeans, gray polo, tool belts that have [some kind of tools]” is a valid observation.
Or “they appear to all be wearing scrubs, as doctors and nurses wear” or “they appear to be wearing clean room suits”
But what isn’t a valid? “….to do maintenance or expand the operation.”
Well, you see a maintenance worker, them doing maintenance isn’t… too far a leap. But again, literally, every non-residential building has a maintenance guy. That ain’t suspicious.
Right?! And we can't be sure he even smelled the weed he claimed to smell. The other things could be verified by being photographed or requesting documents. But the marijuana smell, the thing that probably made the warrant approvable at all, can never be verified. I wouldn't be surprised if he made it up; hell, they do it during traffic stops so why not for a search warrant.
wow that's incredibly obtuse
The icing on the cake: „After retrieving his rifle, the officer is said to have accidentally left a magazine full of bullets on the floor of the MRI room.“
Next to the clown shoes, squeaky red nose, and rainbow afro wig, I assume. Unreal.
Yeah, and the magnet was not to blame for this incident despite how the title of this article reads. Given all the (alleged, I guess) facts of the case, I'm pretty sure sure the cops showed up in a clown car that played Yackety Sax when the horn was pressed.
IIRC the emergency stop vents the liquid helium, that's a lot of the cost I imagine.
The biggest problem is that the magnets will "quench", which is what happens when a superconducting electromagnet suddenly stops being superconducting.
There's a lot of energy stored in that magnet, and when it quenches the energy all turns to heat in a very short time. Any remaining helium will flash boil, turning into an explosive expansion of gas, and the thermal shock will seriously damage the machine
Which, in older machines, might happily pump a fuckton of gaseous helium into the room, potentially creating overpressure and squeezing the door shut while people suffocate.
Yeah. The magnet quench flash boils a bunch of helium which is itself expensive, and presents a nice asphyxiation hazard as well. And then, assuming the quench damaged nothing, you have to set up the magnet again by getting the coils back down to superconducting temperatures... to get there, you end up boiling off a lot more helium. And then you have have to bring an engineer in to get the electrons spinning through the coil again and wait for the wobbles in the current to stabilize.
Or so I think. I work with NMR spectrometers and not MRIs, but it's essentially the same technology.
There's also a finite supply of helium/liquid helium and ...it ain't cheap to refill.
My uncle is a medical equipment installer that installs and calibrates MRI machines.
The issue is more than just the physical damage, which can be expensive, these machines take a long time to calibrate to the local environment. If the electromagnets are damaged, the whole set needs to be replaced, as they are manufactured in matching batches.
It's like if you damage a piston in an engine, it will cause damage to the crank shaft, which will also damage the rest of the engine. It's a helluva job to fix.
I don’t suppose your uncle knows what happens to those magnets that come out…?
You know. Asking for a “friend”. (Okay so this hypothetical friend maybe likes to play with magnets in a totally harmless way….)(edit, yes I know how dangerous they are…. I’ll make sure my “friend” is careful….)
🤣
Just make sure to tell your friend that 600amp wires are expensive and THICK.
Promises promises….
(In the immortal words of some fire-performer-dude at RenFair, “don’t do it at home. Do it at Grandma’s!”)
The primary magnets will be super conducting magnets. Unless you have liquid helium (or liquid nitrogen, if your lucky) to cool it, it will just be an interesting rock.
There’s a facility a few miles from me that makes the LN. used to work at a facility that had a tank farm served by them. Their driver liked to smoke while purging the liquid hydrogen tanks.
And not like, walked over to the smoke shack, nope. right there next to the exhaust vent.
All the helium offgassed instead of being reclaimed so...
